ANTHONY F. MGDONNELL, OF SCRANTON, PENNSYLVANIA.

DO OR-CATCH.

To all whom it may concern:

Be it known that I, ANTHONY F. MCDON- NELL, a citizen of the UnitedStates of America, residing at Scranton, in the county of Laokawanna andState of Pennsylvania, have invented certain new and useful Improvementsin Door-Catches, of which the following is a specification.

This invention relates to door catches and, more particularly, to thatform of catch intended to be fastened to the door and contflact with aretaining member fastened to the oor.

The object of my invent-ion is to provide a simple, cheap and efficientdevice of this character which may be easily applied to the door.

Referring to the drawings: Figure 1 is a vertical sectional view of oneform of the device showing the position of the parts when the door iscaught back. Fig. 2 is a front elevation. Fig. 3 is a vertical sectionalview showing a slight variation in the catch. Fig. 4 is a sideelevation. Fig. 5 is a side elevation showing a method of connectionwhen the door swings close to the floor. Fig. 6 is a side elevationshowing another form designed for a door which swings close to thefloor.

In said drawings, a leaf 1 provided with recesses for the reception ofscrews or bolts to fasten the same to a door has hinged thereto the leaf2 forming a catch. A resilient member of any suitable form butpreferably, as here shown, a coiled spring 3 keeps the leaves normallyin the same plane. WVhile leaf 1 is ordinarily a flat piece it isobvious that it may be of angular form, as shown most clearly in Fig. 6,when it is desired to attach the same to a door swinging close to thefloor. A plate A provided with recesses for the reception of screws forthe purpose of fastening the same to the floor, has pivoted or hingedthereto the latch or catch member 5, and interposed between said plateand latch is a resilient member 6. Plate 4 may be flat or provided withan upturned portion 7, as shown most clearly in Fig. 1, said portion 7acting as a stop for said door. Portion 7 may be integral withSpecification of Letters Patent.

Serial No. 670,086.

said plate 4 or hinged thereto with a resilient member interposed, asshown most clearly in Fig. 3, in which case it tends to grip the leaf 2and prevent rattling of the door.

As will be readily understood, the tension of the spring between plate4: and latch 5 should be light so that the door may be easily swung backinto posit-ion, while that of the spring between leaves 1 and 2 shouldbe suflicient to withstand the weight of the door and any slight strainthat might be put upon it. It is also obvious that the action of therespective parts may be reversed making the member fastened to the doorswing in the opposite direction to that shown and the catch likewiseswing in the opposite direction to the one herein, in which case therelative tensions of the springs would be reversed.

In practice my device is operated as follows: The parts being placed inposition as shown, when the door is opened, leaf 2 strikes against latch5 depressing the same and allowing leaf 2 to pass, when the latchsprings back into place and holds the door open; a slight pull upon thedoor will cause leaf 2 to bend back allowing it to pass latch 5 and thedoor to close.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. A door catch comprising a spring hinge having one leaf adapted to befastened to a door and the other leaf free from the door, and a catchmember having a spring latch hinged thereto that is located in the pathof movement of the free leaf.

2. A door catch comprising a stationary plate having a spring latchhinged thereto, and a door member having a spring hinge connection witha door and adapted to ride over the spring latch.

3. A door catch comprising a resilient catch adapted to be carried by adoor, a resilient latch adapted to be carried by a floor and arranged inthe path of movement of the catch, and a stationary member adjacent thelatch and arranged in the path of movement of the catch.

4. A door catch comprising a door plate, In testimony whereof I hereuntoafliX my a catch havmg a sprlng hinge connectlon slgnature in presenceof tWo wltnesses.

with the plate at one end, a stationary floor plate having a stop at oneend for engaging ANTHONY MGDONNELL' the catch, and a yieldable latch atthe oppo- Witnesses:
